Subject: [PATCH] Include wireless-regdb to resolve #1083 (#1279)

* Add wireless-regdb alongside iwd

Needed for regulatory compliance for Wi-Fi and enabling some bands on some chipsets

* Add wireless-regdb

* Changed location of wireless-regdb install

* configure the wireless-regdom during install

* remove extra newline

* don't unset the variable too early

* also set the region as part of the script

* writing to wireless-regdom requires root

* need to use tee

* changing logic since this is brought in as source

* handle timezones that start with country code already
